Nails for Roof Slates A Comprehensive Guide
When it comes to roofing, particularly with slate tiles, the importance of choosing the right nails cannot be overstated. Slate roofing is not only aesthetically pleasing but also offers durability and longevity. However, the performance of slate roofing heavily relies on the quality of materials used for installation, including nails. This article delves into the different types of nails suitable for roof slates, their specifications, and best practices for installation.
Types of Nails for Roof Slates
1. Copper Nails Copper nails are the gold standard for installing slate roofs due to their impressive resistance to corrosion. They can withstand harsh weather conditions and do not rust, making them ideal for longevity. Copper nails also have the added benefit of expanding and contracting with the slate, ensuring a snug fit even in temperature fluctuations.
2. Stainless Steel Nails For those looking for an alternative to copper, stainless steel nails are another excellent option. They are highly resistant to rust and can last for decades. Stainless steel nails often come in various grades, with the higher grades typically used for marine environments or areas with extreme weather.
3. Galvanized Steel Nails Galvanized nails are steel nails that have been coated with a thin layer of zinc to prevent rusting. While they are a more economical option, they might not last as long as copper or stainless steel in terms of corrosion resistance. Galvanized nails can be suitable for less harsh climates but should ideally not be used in highly corrosive environments, as the zinc coating can degrade over time.
4. Lead Nails Though not as commonly used today, lead nails were historically popular for slate roofing. They offer good corrosion resistance, but they are less favored due to health considerations and the availability of superior materials like copper and stainless steel.
Choosing the Right Nail Size
The size of the nails you choose is critical. Typically, slate roofing nails should be at least 1.5 to 2 inches long. The length allows the nails to penetrate the batten or the wood sheathing beneath the slates securely. A common practice is to ensure that the nail penetrates through the slate and into the underlayment by at least ¾ inch.

Installation Best Practices
Proper installation of nails for roof slates is crucial in ensuring that the roofing system performs effectively over time. Here are some best practices
- Nail Placement When installing slate, nails should be placed just above the slates and driven into the roof deck, as opposed to the slates themselves. This allows for proper water drainage and prevents potential leaks.
- Avoid Overdriving It's essential to drive the nails in just enough to secure them without overdriving. Overdriving can cause the slate to crack and jeopardize the integrity of the roof.
- Use the Right Tools Use a hammer or a pneumatic nail gun designed specifically for roofing installation. This ensures that the nails are driven in at the correct angle and depth.
- Check Local Building Codes Always consult local building codes and manufacturer recommendations for nail specifications and installation practices. Some areas may have specific requirements based on climate or local conditions.
Conclusion
Selecting the right nails for roof slates is integral to the longevity and functionality of your roofing system. Copper and stainless steel nails stand out as the most reliable options, offering superior corrosion resistance and durability. Proper installation techniques and adherence to best practices will ensure that the slate roof remains intact against the elements. Whether you are a professional roofer or a DIY enthusiast, understanding the importance of high-quality nails will help you achieve a roof that not only looks beautiful but also stands the test of time. With the right materials and methods, your slate roof can provide decades of protection and aesthetic appeal.
